Though it was widely reported that Robin Williams killed himself, but a horrifying & debilitating disease! As we all know comedian Robin Williams hanged himself in his California home in August 2014, and the news of his death was met with incomprehension around the world.

And there was endless speculation that depression was the driving force for him to commit suicide. In fact, most of his colleagues and friends of Williams came forward to allege that depression contributed to his severe mental state. But on Tuesday, his widow Susan set the record straight. She told People Magazine that it ‘wasn’t depression that killed him’ . but debilitating brain disease called Lewy body dementia.

It was not depression that killed Robin!

“It was not depression that killed Robin,” Susan told People magazine in one of her first interviews since losing her husband. “Depression was one of let’s call it 50 symptoms, and it was a small one.”

Susan spoke with ABC New’s Amy Robach in an emotional interview that aired in part on Tuesday’s Good Morning America, and reveals that she believed dementia is what “killed” her famous husband — though she never suspected he would take his own life.

“I mean, he was sick and tired of what was going on, absolutely,” Susan says, adding that “Lewy body dementia killed Robin.” “It’s what took his life,” she continues, “and that’s what I’ve spent the last year trying to get to the bottom of: ‘What took my husband’s life?'”

Lewy body dementia is a debilitating brain disease called or dementia with Lewy bodies (DLB) that took hold of Williams, and probably led him to suicide.
